1 The functionality of the safety systems stated
in SOLAS regulation II-2/23.6 should
be available from the safety centre systems under any envisaged emergency
situation (other than casualty affecting the safety centre itself)
and should be efficiently managed from the safety centre without distracting
the bridge teamfootnote. The functionality
of these systems within the safety centre is specified in appendix 1.
2 The safety centre may or may not be part of
the navigation bridge. The safety centre may be considered as part
of the navigation bridge when it is arranged as examples indicated
in diagrams (a), (b) and (c) of the illustration in appendix 4. In case of arrangements
such as in diagram (d) in appendix 4, the safety centre should be
considered as not being part of the navigation bridge.
3 Where the safety centre is part of the bridge:
-
.1 it is acceptable to consider nearby members
of the bridge team as being sufficient to make the safety centre "continuously
manned";
-
.2 alarms in the safety centre should be audible
at the conning position for responsible members of the bridge team
to make them aware of an alarm condition; and
-
.3 at least one member of the on-watch bridge
team should be properly trained and authorized to take appropriate
initial and interim actions in the event of an emergency or in response
to an alarm, until the safety centre is fully manned.
4 Where the safety centre is not part of the navigation
bridge, it may or may not be continuously manned.
4.1 When the safety centre is continuously manned
the functionality of the systems listed in appendix 2 should be duplicated on the Navigating Bridge.
4.2 When the safety centre is not continuously
manned, there should be the capability on the navigation bridge to
alert the bridge team of developing shipboard emergencies, to respond
to them appropriately by taking initial and interim actions and to
allow necessary monitoring functions after the safety centre is manned
by properly trained persons. Therefore, the functionality of the systems
listed in appendix 3 should be
duplicated on the navigation bridge.
5 The hierarchy of control between the navigation
bridge and safety centre should be specified within the shipboard
safety management system. In this respect:
-
.1 an adequate number of properly trained personnel
should be available for immediate response to the safety centre in
an emergency while maintaining an effective navigational watch;
-
.2 the duties of the safety centre personnel and
navigation bridge personnel should not overlap; and
-
.3 coordination of emergency management actions
and communications should be assured through established emergency
procedures, harmonized with the onboard decision support system required
by SOLAS regulation III/29.
6 In carrying out the various functions on the
navigation bridge and safety centre an integrated computer technology
may be used.
7 When such a system is utilized:
-
.1 the hierarchy of control of the various computer
stations and locations should be clearly documented;
-
.2 the computer system and programming should
be designed to assure that failure of the system does not cause the
loss of any of the ship's safety systems; and
-
.3 the operational status and failures of the
computer system or its communications should be indicated.
8 Controls and monitoring of safety and security
related systems other than those listed under SOLAS regulation II-2/23.6 may also be located
in the safety centre.
